ESS Energy Storage System

The system serves for the utilization of braking energy in municipal mass transit.Electric energy savingBraking vehicle generates electrical energy. In case that there is no other vehicle
in the supplying section to consume the generated energy, it is wasted in a form
of heat in the brake resistor. Using the ESS installed in the substation or in the
container by the tracks of municipal mass transit system this energy is accumulated
in supercaps and then supplied to the accelerating vehicle. Stabilization of the overhead line voltage
High consumption of electric energy in the vehicle results in the voltage decline in
the long overhead line which can put the vehicle out of operation. ESS installed
in the problem point supplies the energy accumulated in supercaps to the overhead
line and thus minimizes the undervoltage. Advantages of the Energy Storage System:Saving electrical energy through the utilization of vehicle braking energy
Stabilization of the overhead line voltage
Modularity of solution
Easy installation of the equipment
Not dependant on the high voltage network
Not dependant on the traction substation
High charging and discharging performance due to supercap technology
Regular evaluation of electrical energy savings using data remote transmission

Energy Storage System has been declared by jury the winner of the prestigious
scientific journal "L'Usine Nouvelle" in the category of sustainable transport at 19.5.2015.
